MATLAB: How to assign variables.

Question

Hi. I am a beginner in Matlab.. wanna seek for help from Matlab pro…i wrote codes: {i=1:5; j=5; x = [0.1 0.2 0.3 0.4 0.5]; for i = 1:5 for j = 5 X = x(i:j) end end}

and the outputs are:

X =

    0.1000    0.2000    0.3000    0.4000    0.5000

X =

    0.2000    0.3000    0.4000    0.5000

X =

    0.3000    0.4000    0.5000

X =

    0.4000    0.5000

X =

    0.5000

How can I assign a variable X(1),X(2),…,X(5) for each X respectively i.e X(1)=[0.1 0.2 0.3 0.4 0.5], X(2)=[0.2 0.3 0.4 0.5] and so on…. Your cooperation is very much appreciated

Answer 1

You can do this using cell arrays:

x = [0.1 0.2 0.3 0.4 0.5]; 
for i = 1:5
    X{i,1} = x(i:end)
end

Then, you can access the contents in each cell using curly brackets:

X{1}
